Function alternative

MIC29150-12WU

Microchip Technology

Functional higher-current alternative to the obsolete onsemi NCP1117ST25T3G. Microchip MIC29150-12WU is a 1.5 A high-current LDO (50% more current than NCP1117's 1.0 A) in TO-263-3 (3-pin D2PAK). NOT pin-compatible (TO-263 vs SOT-223) — PCB redesign required. Same low-dropout topology and 3-terminal LDO architecture. Use when the application needs >1.0 A and can accommodate the larger TO-263 thermal footprint. Note: 12 V fixed output; for 2.5 V fixed order MIC29150-2.5WU.

MIC29150-12WU is indexed here as a mapped pin-to-pin replacement for MIC29150-12WU with package, lifecycle, stock, MOQ, datasheet, and key attribute context for buyer review.

Cross-reference FAQ

Replacement Part Questions

Short answers for teams reviewing MIC29150-12WU replacement and equivalent-part options.

What is a cross-reference page for MIC29150-12WU?

This page groups mapped replacement options for MIC29150-12WU so buyers and engineers can compare alternatives before requesting a quote or approving a substitute.

Does a mapped alternative mean a guaranteed drop-in replacement for MIC29150-12WU?

Not automatically. Cross-reference mapping helps shortlist candidates, but package, electrical behavior, qualification scope, and approval rules still need to be checked before release.

Which parameters should teams compare first for MIC29150-12WU alternatives?

Start with package, series, key attributes, lifecycle status, stock position, datasheet access, and the mapped pin-to-pin or cross-reference note. Then confirm application-specific requirements in the datasheet and RFQ stage.

Can I request a quote for an alternative to MIC29150-12WU?

Yes. Use the product links or RFQ actions on this page to request pricing, availability, documentation, and sourcing support for any listed alternative part.

Is MIC29150-12WU obsolete, and what replacement should buyers review first?

Check the lifecycle row on this page first. If buyers need a fast starting point, the strongest mapped replacement currently surfaced here is MIC29150-12WU, followed by the other alternatives shown in the comparison table.
